Last winter restored our gardens in San Diego. That included bulbs.
Of special note in high summer was, for many years, Amaryllis
belladonna. For five years little, if anything, was seen of these
lovely creatures. I mean, no flowers and no foliage. Clumps with
over a hundred bulbs each lay dormant. Finally, and not until
mid-July, they burst up. After their absence for five years it was a
wondrous sight. Other South Africans had flowered once or twice over
that period but A. belladonna had not. The clump sizes had not
changed but the individual bulbs had shrunk somewhat. Steady, non
torrential winter rains made all the difference.
