LABURNUM

T. An attractive feature of any garden, large or small, for its dainty foliage and graceful racemes of yellow flowers, which are in profusion. A good species is Laburnum alpinum (the Scotch laburnum), which should be planted in October in a sunny position and average soil, staking well and keeping well watered till established. This may reach 25 ft. It blooms a week or two later than the common laburnum (L. vulgare) which flowers in late May and early June. L. vossii has extra long racemes of flower. Laburnums are easily increased by seed sown outdoors in spring. Self-sown seedlings occur. Although some plants are exceptionally long-lived, others may suddenly collapse for no apparent reason. The graft hybrid or chimera Laburnocytisus adami (a fusion of Laburnum anagyroides and Cytisus purpureas) bears coppery-pink flowers, with periodic reversions to either parent. Note that all laburnums are highly poisonous in all their parts.

LACHENALIA or CAPE COWSLIP These are attractive bulbous plants flowering in February and March, only needing a minimum temperature of 45 degrees F. The small, tubular flowers are borne on 9—12 in. spikes. Burnham Gold bears up to 20 deep yellow flowers on plum-purple stems. Lachcnalias should be planted in late August or early September in John Innes Potting Compost. They are suitable for hanging baskets. Increase by division at the same time.
