For filling in between the most important plants we must have something that grows higher than the centre piece without taking much room. Therefore, bulbs are best, as a rule. I would reject hyacinths and early tulips because they are not permanent enough; also English and Spanish iris. The best, in my opinion, are:

Crown imperial.........

.......Early April

Daffodils...........

........Late April

Poet's narcissus .........

........May

Darwin tulips........

...... . . May

Madonna lily........

........June

Lilium elegans......

........July

Lilium Henryi..........

........Aug.

Lilium speciosum.........

........ Sept.
