Garden plant type of yucca hospital regularly wanted (7)
I believe the answer is:
fuchsia
'garden plant' is the definition.
(I've seen this before)
'of yucca hospital regularly wanted' is the wordplay.
'regularly wanted' indicates alternate letters (letters removed at regular intervals).
'of'+'yucca'+'hospital'='ofyuccahospital'
The alternate letters of 'ofyuccahospital' are 'FUCHSIA'.
'type' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for fuchsia that I've seen before include "Flowering shrub" , "Ornamental flowering plant - reddish-purple" , "One blooming" , "If such a plant is a showy flower" , "Bush" .)
