Birdie, you're so young you'll never retire! Bob Fogel (Louisiana from Utah) fellow was a school mate in Oregon where we grew up by the way. He's an expert in fungi, etc...in case you need a fungi expert. Happy Gardening. Looks you had a great time in Hawaii - one of my more favorite places on earth. Not a big fan of Oahu but I do love all the other islands.
Have fun in Hawaii! I haven't been since 2006, but we loved it! Kauii (not sure if that's spelled correctly), was our favorite island. All the ferns that just grow wild there amazed me. I told my husband, we have to buy those, & they just grow everywhere here wild! Make plenty of pics to show us! I believe I visited every nursery & garden in Kauii & Mauii. I brought home some plants & seeds. Yes, some of the plants looked like they needed deadheading, so I helped, even though if they would have found the seeds, I would have had to pay a hefty fine. They all grew for me, but the cold got the trees once I put them in the ground. I should have kept them in pots. :(
"Yes I know the plant well, they love our climate in Australia, a fast grower, will cover an old ugly fence in one season. Loves a good hair cut and then flowers again.It has a dormant period for a couple of months during winter, but stays alive."
"Keryn, This variety of plumbago will not survive zone 5 winters. I bring winter it over in amy attic in a sunny window. It isn't a vine more like a small shrub. I do have another hardier variety. It is a darker blue. Love them both."
