March is still somewhat dominated by aloe flowers, but for pure mass of color, the Mesembs have taken over. Some of these ice-plant relatives blanket the gardens and landscapes of southern California and other Mediterranean climates this month and next with overpowering displays of color. Additionally, this is the first month the cacti really show off in numbers, though Mammillarias have been showing flowers off and on ever since January. As usual, Agaves and Aeoniums are flowering in large numbers, but now Echeverias are adding into the mix. Not to be left out are the Puyas, terrestrial bromeliads that are often planted alongside cacti and succulents thanks to their drought tolerance and similar habitat preference.

Bowiea volubilis flower

One can search around carefully for small, delicate flowering wonders like this 0.5cm Bowiea volubilis (Climbing Onion) flower

Aloes:

Aloe africana

Aloe africana flowers Aloe africana flowersclose

Aloe africana is one of the most prolific of all the tree aloes this month, cranking out many flower stalks per plant sometimes. This aloe can be identified by its typical upward swoop of the opening flowers

Aloe California Aloe claviflora Aloe conifera

Aloe 'Blue Elf' is a common sight blooming throughout southern California in March (left); Aloe claviflora (middle) is a much less common sight; Aloe conifera (right) is represented in some of hte botanical gardens

Aloe debrana Aloe debrana closer

Aloe debrana is fairly well represented at several botanical gardens, as well as private gardens, in southern California and this species is a wonderful landscape aloe when planted in groups. Some gardens may have it identified as Aloe behrana (old name).

Aloe debrana close up Aloe petricola

Aloe debrana flowers close up (left); right is the end of Aloe petricola flowering time... this is really a February flowerer, but one can usually catch glimpses of it in March as well (right) . It is a welcome change from the predominance of red flowers one seems to encounter in aloes in March (this is red flower month to me)

Aloe camperi Cornuta Aloe spicata

This curious plant, Aloe camperi 'Cornuta' is another fairly common bloomer seen in southern California botanical gardens in March (left), but what it's relationship to Aloe camperi is unclear, as it is a very different looking plant (huge in comparison), had different colored flowers, and blooms at a different time of year... are they really related? Makes great mass plantings, too, though. Left is Aloe spicata (which could just as well be Aloe vryheidensis for all I can tell), another later-in-the-season bloomer.

Aloe globulogemma

Aloe vera Aloe aculeata Aloe pratensis

Aloe vera blooms in March, but many other months as well (left); Aloe aculeata blooms in March in my yard (center) but usually a bit earlier elsewhere for some reason; and Aloe pratensis (right) is a nice aloe to have 'end the flowering season' with
