    Default Knockout roses and Rosa rugosa

    I have two questions really.

    Next year, I want to landscape my yard along the road, and I'd like to plant a lot of Rosa rugosa, which is salt-tolerant. I've never seen any, though, at my local nurseries. Everyone seems to carry knockout roses. They look a lot like Rosa rugosa, but are they the same thing?

    Also, I went to the beach a few times this summer, and the seashore was covered with Rosa rugosa for miles around. I'm going to try planting them. However, I'd really prefer full-size bushes (which is why I'm curious about the knockout roses.) Does anyone know how quickly rosa rugosa grows?

    Thanks!

    you can buy the rosa rugosa online at nursery. It hasnt been sold as much lately as it is considered an invasive plant that spreads & grows very quickly.

    I've grown some on the north side of my house in Maryland. They were 1-2ft when planted. They grew to 4-5ft and filled out nicely within the first growing season. I believe the Knockouts are a different variety, a hybrid - could be wrong. Rugosas, as you probably know don't really require any care. I haven't seen my bees being especially interested in them in case that matters to you. They are very fragrant - not overpoweringly so.

    No, Rosa Rugosa are mostly wild varieties of rose bushes from Asia that bloom once a year for about 3 weeks in May. Spread mostly from root stock and grow to 3 - 4' tall. Not a great bee forage plant, but bees will visit them some. Very, very fragrant. Some selective breeding has occurred, a great white flowering variety is "Blanc Double de Courbet". I also like the Purple flowing "Purple Pavement" variety. Big nurseries sometime have them in early spring. I order root stock over winter for spring planting in April.

    Knockout roses are a very durable hybrid that bloom all season long. I've never seen bees visit them. Most varieties are not fragrant.

    I have knock-outs here in Texas. Tremendously sturdy in our climate. If I had it to do over again, however, I would have planted something that the bees like. They've never been interested in my knock-outs.
