Though I dearly love my plants, I have never thought of them as male or female. The plants I grow produce flowers of both types or with both parts. Allspice is an exception but I still just think of 'it' as just 'Allspice.' However, you should not feel that you are unique in this as it is not unusual for people to speak of their plants with pronouns expressing gender.
Interestingly enough, Angraecum Sesquipedale was once known as the 'King of Angraecums' and Angraecum Magdalenae was once known as the 'Queen of Angraecums.' Piper Nigrum is sometimes called the 'King of Spices' and Elettaria cardamommum is sometimes called the 'Queen of Spices'. Orchids are sometimes given clonal names that make them seem male or female, too.
