This bulb is "like the crocuses, the flowers come naked, but the leaves shoot up in the spring...and when they start to ripen and die off in late spring, they turn various nasty shades of yellow and appear to be in agony. This does not bother me, since my thyme and rue more or less ameliorate, or at least obscure, these goings on, but plant colchicums where the ripening foliage does not bother you.... Where the colchicum leaves die down, the earth retains a sort of funnel shape - a hole where the sheaf of leaves used to be. It struck me that water might collect in such a place, but no, these hollow channels are said to make it easy for the flowers to emerge in September, so perhaps we should not worry." |

For herbaceous beds and shrubberies, the stronger-growing kinds of crocuses can be planted in large clumps and drifts. Soil should be removed to the depth of 6 inches and the corms laid on the bottom of the hole at the space of an inch from each other. It is customary to plant Crocuses as edgings to borders in rather formal lines or circles, but a charming effect is produced by planting some hundreds of one kind under deciduous shrubs, or at the back of borders between clumps of strong-growing herbaceous plants that do not cover the ground with their leaves earlier than the middle of May, and thus allowing time for the Crocus leaves to mature in an open space. The Dutch Yellow, in my opinion, never looks better than when planted in a generously planned drift, towards the back of a large border, or round the stem of a leafless Rhodendron molle, Deutzia, etc. All the florist's forms of Crocus vernus are suitable for this work, and Crocus tomasinianus once planted should be allowed to spread naturally by seed as far as it will under groups of roses or other summer-leafing shrubs. Crocus speciosus is the best of all the autumn-flowering Crocuses for wide plantings, and does not object to an occasional digging over of the bed and the consequent deep burial of the corms. Only the stronger growers should be tried in grass and none succeeds better than the forms of Crocus vernus and the Dutch Yellow. I have always advised that they should be kept separate, or at any rate the yellow planted only among white varieties; but a charming planting of irregular colonies, each of one kind, under some trees in a friend's garden taught me that if the yellow are planted in separate groups; instead of being scattered among the purples; they can be very effective. The quality of grass differs so greatly that my rather poor success with the many species I have tried in a rough meadow need not discourage others with a finer brand of turf. I used to give bundles of rogues and mixed seedlings to Mr. Wilks to plant in his wild garden at Shirley, and in his grass they flourished and spread most delightfully. The soil there is a fine sand, and he used to say of it that it was so light that if he threw it up in the air it would never come down again, and naturally the grass on it is scanty and fine. Where the turf is not coarse, and the ground well drained and open to sunshine, I advise planting Crocus tomasinianus, Crocus aureus, Crocus chrysanthus, Crocus sieberi, Crocus versicolor as well as Crocus vernus for spring, and Crocus kotschyanus, Crocus speciosus, Crocus nudiflorus and Crocus longiflorus for autumn."
How to tell a Colchicum from a true Crocus?
The following diagram shows the parts of the Crocus and Colchicum. The following year the corm uses the hole left when the Perianth Tube dies off to push up a new tube with its flowers and leaves. It is therefore better if you do not disturb the ground once you have planted these corms.
This diagram from A Handbook of Crocus and Colchicum for Gardeners by E. A. Bowles Ma.A., F.L.S., F.r.E.S., V.M.H. published by The Garden Book Club, 121 Charing Cross Road, London WC2. in 1955. It has the following excerpt on Colchicums:- "The greater number of the handsome members of the genus Colchicum are easily grown, and the chief trouble in a garden arises from the amount of space required in spring and early summer for their coarse leaves. In autumn the rosy lilac, white or tessellated flowers can never be too numerous, come where they may; but in spring it is almost annoying to watch the unfolding of those great leaves. They expand enormously with the April showers, rise up rapidly on tall shoots and are then ready to fall outwards and sprawl over neater-growing plants; that we realise too late have been planted too near the Colchicums. They would make a good edging to beds of shrubs or tall herbaceous plants but for their aggravating habit of beginning to fade and collapse in the first warm days of June.... The dormant period of a Colchicum is short. The leaves fade after the ripening of the seed in June, and the corm matures soon after. Those that flower in autumn are ready in August to form new roots and push out flowers. Some species can flower satisfactorily at their natural season without being planted or supplied with any moisture. I have seen a gay show of flowering Colchicums in cottage windows in Cornwall provided by corms laid in a row on the ledge of the bay window. It is very unusual that a plant brings flowers to perfection while without active roots to supply moisture to the expanding cells. Colchicum byzantinum can bear 12-20 flowers in a long succession and without active roots. Gathered flowers of many species will last fresh for several days without being placed in water. The leaves differ greatly in form and size among the species and also as to the time of their appearance. In most autumn-flowering species such as Colchicum autumnale, Colchicum speciosum, Colchicum byzantinum and Colchicum agrippinum they do not appear before the following spring and are large and broad; in most of the winter or early spring flowering species they are narrowly linear and accompany the flowers. Colchicum kesselringii and Colchicum szovitzii have the narrowest and Colchicum byzantinum and Colchicum macrophyllum have the longest, a foot long and 6 or more inches in width. In most species they are glabrous (glabrous is without hairs), in others pubescent (pubescent is shortly and softly hairy) or ciliated (ciliate is with regularly arranged hairs projecting from the margin) on the margins. As the leaves mature in the end of May the large seed capsules are revealed in the cup formed by the bases of the 2 or 3 innermost leaves. The seed vessel is formed of 3 distinct carpels, free in their upper half but generally united below. When ripe they open at the summit and the round, thick-coated seeds escape. From the observations of Professor Rolf Nordhagen,..... it seems probable that the seeds of Colchicum are distributed by ants. He found that those of Colchicum autumnale and Colchicum speciosum are covered when ripe with a sugary layer which is attractive to ants, and he watched ants remove 23 seeds from a capsule of Colchicum speciosum in 12 minutes. Apparently ants consume the edible outer coat, but are deterred by the presence of colchicine from damaging the embryo and cotyledon. The large-flowered species that blossom early in autumn are easily grown, and so are a few of the spring-flowering forms. Those that blossom in mid-winter, like Colchicum variegatum, are not easily kept in health, and some beautiful spring-flowering kinds are difficult to keep alive in the open. Colchicum speciosum and its varieties are among the handsomest of bulbous plants and should be in every garden where room can be spared for the leaves in spring. A rich, deep and rather moist soil suits most of the species best, but they will thrive in well-drained slopes of the rock garden also. Colchicum autumnale, Colchicum byzantinum, Colchicum agrippinum, Colchicum laetum and Colchicum speciosum will grow in grass, but in view of their poisonous nature it is not wise to plant them where cattle graze, and the seed-pods and leaves should be gathered out if the grass is to be used for hay. However, after making many enquiries I have been unable to learn of a definite case of cattle poisoning by Colchicum, and it seems probable that beasts avoid eating it just as they shun buttercups. When planted in grass increase is slow, and as with Crocuses, if it is desired to obtain a stock, the roots should be planted in well-tilled ground and divided every second year. In a wild state, the corms of most of the species are found at a great depth, but in garden ground they do best with the cap of the tunic reaching the surface." |

There are 720 roses in the Rose Galleries; many of which have the above series of pictures in their respective Rose Description Page. So one might avoid the disappointment that the 2 elephants had when their trunks were entwined instead of them each carrying their trunk using their own trunk, and your disappointment of buying a rose to discover that the colour you bought it for is only the case when it has its juvenile flowers; if you look at all the photos of the roses in the respective Rose Description Page!!!! |
