Hi.To be fair alot of birds do look and sound different.Even the plain brown ones have some differences.But with the brown ones it is harder to tell them apart ,yes.Wow,your job sounds like a dream job if you love plants and animals.Even though most jobs have good and bad points though.What do you like best about your job.
Scabious is attractive yes and distinctive looking.I have a decent plant knowledge from reading books,visiting gardens and gardening courses.Plants and mammals are facinating.
Lilies,climatis,tigrida pavania,Dahlias(Single and collerette),Zinnias,Hostas(varigated ones) and Cannas( with colour folliage) are some of my favourites but its a long list.Im actually growing them all at the moment.
