Gardening expert .......

NOT !  but I do sometimes like trying to grow from seed. I understood that this would be difficult with a Bottlebrush plant.
Anyway last year as I dead headed the flowers I put some on the kitchen window sill where it is sunny. After a while they threw the seeds out which I planted and Voila I have some more shrubs !  If you look through the Square window (Play school) you will see the Mammy shrub which I bought 30+ years ago in Aberdeen,
Gardening lesson over.Sorry but its cold and wet here today so staying put !!! :)
